As title mentioned, I’m a heavy spin baseliner that was using a 130/16 RPM Rough 200m coil for the past couple months. I strung at 24/23 kg (~53lbs) but after a 5 to 8 hours I’m having lots of issues controlling the ball and hitting long. Any recommendation for a high-end string that can hold sufficient tension for 10 hours. I normally break strings at 10-15 hours.
